Scripting Issues...

[Ramon]

Hi,

My problem is that my script cannot access variables that are stored in
~/.bashrc.

Here is (part of) my local .bashrc file:
$ cat ~/.bashrc
myvar="abc"

And here is my small script:
$ cat myscript.sh
#!/bin/bash
echo "$myvar"

The $myvar is loaded correctly:
$ echo $myvar
abc

But the script is unable to display it...
$./myscript.sh
$

For some reason nothing is displayed when I execute myscript.sh. Is
there a solution for this problem?

Ramon.

Try:

export myvar="abc"

instead

myvar is [a] local [variable] to the running bash and not part of its
environment variables which are "exported" to any new program.

See above.

That is a local variable, you need to export the variable to other processes-

export myvar="abc"

Test your script after that.
